What each ingredient does

Home-brewed yeast
Provides the living culture that leavens the dough.
Wheat flour
Forms the lumps that store the yeast and later feed the dough.

The step that matters

Drying the lumps completely. If the lumps stay damp, the yeast can spoil or ferment unevenly in storage. Full drying keeps the culture stable until it is needed.
